Title: Large area heater element - consists of metallic fibrous material sintered together with individual fibres
Inventor: SCHUMANN ERWIN DIPL ING
IPC: H05B3/00
Filed: 1974-05-04
Abstract: Normally, heating elements consists of coiled wire which demands some space in order to produce a sufficient heat area and also to provide the necessary length for the electrical resistance. Tape elements give greater heating surfaces than wire yet give rise to the problem of achieving the necessary electrical resistance since they are by definition relatively wide. The present solution is to provide sintered together metallic fibrous material with regularly or irregularly arranged individual fibres. The porous volume can be as high as 98% so that the specific electrical resistance of the basic metal used for the fibrous material can be increased by a factor in the region of 50.

Title: Trouser press with uniform pressures - using spreader plates supported along both longitudinal edges by resilient members
Inventor: KOETTER GUSTAV
IPC: D06F71/29
Filed: 1974-07-29
Abstract: Trouser press of parent patent has a fixed and a movable supports both of which are split to permit movement of the supports towards the trouser leg creases. Movable support forming the pressing plate is composed of plate elements supported by resilient members carried by the fixed support and allowing the spreading movement of the elements when the pressing plate is displaced in the direction of the fixed support. In the addn., the plate elements also have their outer longitudinal edges supported by resilient members having like configuration and deforming in the same direction when the pressing plate is displaced. The pressing plate thus exerts a uniform pressure over the whole plate area.

Title: Determn of solids content in liquids - using drying and irradiation followed by combustion to distinguish organic and inorganic constituents
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G01N33/18
Filed: 1974-12-02
Abstract: Process for determining the inorganic and organic content of liquids filters a continuous sample stream onto a continuous belt and checks the quantity by an irradiation method. The samle stream is fed uniformly onto the filter band, dried and irradiated, which gives a value for the combined organic and inorganic material. The organic material is then destroyed by heating to its decomposition or combustion temp. and the residual material then rechecked giving the inorganic content. The filter band can move at a controlled speed and the sample stream is at a controlled rate. The belt speed is slow enough to ensure strong concn. of the solids on it. Used to check the solids content of effluents and sewage. A system for checking total solids using batchwise sampling is known. This system allows for continuous sampling and for distinction between organic and inorganic content.

Title: Activated carbon fibre filter beds - which remove both aerosols and polluting gases having fibres of less than 1 micron dia.
Inventor: SPURNY KVETOSLAV
IPC: B01D53/02
Filed: 1975-04-19
Abstract: Aerosol filter consists of a fibre mat of carbon fibres the dias. of which should not exceed 1 um which are regularly packed, uniformly and parallelly orientated, and then activated. The process for making this filter can consist of atomising a soln. of organic polymer and pyrolysing the resultant fibres by heating. They are then collected on a moving belt and oriented by an electric field. Finally resulting filter mat is activated. Alternatively the mat can be formed from plastic fibres and converted into a carbon fibre mat by subsequent pyrolysis. The carbon fibres can be dispersed in water and then laid as a mat by deposition from the water slurry. To act both as an aerosol filter and as an adsorption bed for compds. which cause pollution. 99% efficient aerosol filters are known, using synthetic fibres. Similarly activated carbon granule adsorbent beds to remove harmful cpds. such as CO, CO2, H2S, AsH3, HCN etc. are known. The filter described efficiently fulfils the roles of both these processes.

Title: Magnetostrictive transducer producing digital coded voltage output - uses induced pulse principle and includes two sonic transmission units
Inventor: RUNGE RUEDIGER
IPC: H03M1/00
Filed: 1975-04-29
Abstract: A relative mechanical single axis displacement transducer which converts relative displacement into a small digital encoded voltage pulse train uses a sonic magnetostrictive induced pulse principle. The transducer is an improvement on the traditional resistance, capacitance and inductance based displacement transducers in that it produces directly a digitally encoded output. Two sonic transmission units are used, with a magnetostrictive pulse induced in one (A), and the pulses induced in the second (B) used to detect displacement between the two elements. The two elements lie together, separated by a thin insulating rubber film. The number of pulses detected in the second element represent the overlap, and so the relative displacement of the two elements. The device is applied to a thermometer, when the two elements are the conducting liquid and the specially constructed containing tube. Angular displacement can also be measured with the elements in this case arranged round the circumferences of an outer, stationary and inner movable disc.

Title: Variable tariff parking meters - allow different day and night tariffs using central control with time selected output clock frequency
Inventor: ARZT FRIEDRICH
IPC: G07F17/24
Filed: 1976-02-20
Abstract: A control network is used for undercover parking meters which allows different tariffs to be charged automatically during the day and night. The parking meters (1) each contain a display clock which is set back by an amount corresponding to the money inserted. The clocks are driven by pulses over a line (2) from a central control (3). This contains a clock generator (4) producing a signal at several megahertz and a frequency divider (5) which provides several outputs at different frequencies. Each of the outputs is amplified (7) and switched (8) to the clock supply line (2) by a time dependent switch (9). Each parking meter clock returns to its quiescent state from a given displacement over a time period determined by the central control time switch (9), varying the tariff as required.

Title: Flexible controls for vehicle - with coiled hydraulic hoses between hand held controls and vehicle
Inventor: SHIBER SAMUEL
IPC: F02B1/04
Filed: 1976-06-15
Abstract: The sport and pleasure vehicle is self propelled and is steered by the operator shifting his weight on the support platform. Such vehicles include self propelled roller skates, skis, etc. In order to provide a flexible linkage between the hand controls and the engine and brakes a hand grip (12) is linked to the vehicle by coiled flexible hoses (156). Hydraulic master cylinders in the hand grip are thus coupled hydraulically to slave cylinders on the throttle and the brakes. The hoses are coiled so that they do not drag on the ground. A simpler layout has one hose for the throttle control and an electric wire through the hose for the brake control.
